Invited paper

A coherent picture for magnetic response of heavy fermions is provided on the basis of neutron-scattering results and the self-consistent perturbation theory. It is shown that the momentum dependence in the magnetic response is mainly due to the RKKY interaction. With growing itineracy of f electrons, another exchange interaction becomes relevant. The tiny ordered moments in some heavy-fermion systems are ascribed to dominance of the itinerant exchange.

While the effective mass of heavy fermions governs their thermodynamics, the optical properties are dominated by the characteristic relaxation rate which is expected to scale inversely with the effective mass. At the relaxation rate clear features, the so-called Drude response occur in the real and

Using symmetry considerations and exact diagonalization techniques, we examine the heavy-fermion behavior in an eight-site periodic small-cluster t-t'-J model on the fcc lattice. An interpolation scheme is introduced to construct an interface structure. The ground-state properties and the heavy-ferm
